This invention relates to selecting and actuating mechanism; and ithasfspecial reference to a mechanism for selectively operating one ormore of a series of parts.

The invention may be applied'to various uses. For purpose ofillustration we have chosen an embodiment wherein one or more of anumber of parts may be selectively operated from one adjustment toanother. These parts may typify any parts to the selective operation ofwhich the present invention may be applied irrespective of what thefunction of such parts may be. 1

An object of the invention is to provide a mechanism capable ofapplication to the purposes above mentioned and to any other usefulpurpose which the invention may satisfactorily serve.

A restatement of objects of the invention including. specific referenceto parts shown in the drawings will be of advantage. There is a seriesof parts 1 which are capable of longitudinal movements in stationaryguides 2 and each of which controls a movablepart 3 having on each end aroller 4. The rollers 4 are mounted on studs 5 which project through theparts 3, so that the rollers 4 are at one side of the parts 3 while thestuds 5 project through said parts"3 and into slots 6 in a part 7 thatis to be moved from one position to another.- As will hereinafter apear, the present invention is designed and a apted to operate anyselected ones or all of the parts lat a single operation and therebyoperate any selected ones or all of the parts 3 into engagement'with alongitudinal movable'opcrating bar 8, by longitudinal movement of whichall of the parts 3 that are engaged with said bar 8 will be movedlongitudinally and will thereby move the parts 7 longitudinally from oneposition to another. A principal purpose and object of the presentinvention is to provide devices and mechanisms where- I by selected onesor all of the parts 1 may be i the parts 3 that wereengaged with saidbar 8 "as aforesaid; and thereby move longitudinally from one positionto another the parts (Figs. 6 and 7 with which the parts 3 areconnected. With this object and purpose of the invention in view we nowproceed to a description of the illustrated devices and mechanismstherefor.

A lever 9 is connected by a pivot 10 (Fig. 13) to a bracket 11 attachedto the upper end of each of the parts 1. Each bracket 11 has a pairoflaterally projecting arms 12 spaced apart, one above the other, andforming a space designed and adapted to receive the rollers 4 on thecorresponding part 3. That is to say, in one position of the part 3, theroller 4 at one end is between the arms 12 of the bracket 11; and, inthe other position of the part 3, the roller 4 at the opposite end ofsaid part 3 is engaged with said bracket 11 12). From this it isapparent that, if one end of the lever 9 be fulcrumcd and the other endof said lever be moved in a direction away from the part 1, said part 1will be moved thereby in one direction from a starting position; and,when the lever 9 is returned to its initial position, the part 1 willthereby be moved to its starting position. Such movements of the part 1including the bracket 11 operate the part 3 first into engagement withthe operating bar 8 and then out of engagement with said bar 8. Aboutmidway of its length each part 3 is provided with an upwardly extendedarm 13 having on its upper end a lateral projection 14 which, in thelower position of the lever 9, seats upon the upper edge of the part 7(Fig. 1), causing one of the projections 5 to be at the lower end of itsslot 6 and the other projection 5 to be at the upper end of its slot 6.The operating bar 8 has a notch 15 for each arm 13, which notch is alsoextended through a plate 16 attached to said bar 8 and having lateralprojections 17 on its lower edge. In the initial or starting positionsof the devices above described, one of the notches 15 is above each ofthe arms 13 so that, when any or all of the levers 9 are selected andoperated by fulcruming one end of the selected levers and raising theopposite ends thereof, said levers will raise the connected parts 1 andthereby move the arms 13 into the notches 15. Obviously, if an arm 13 isengaged in the corresponding notch 15 and the bar 8 be then movedlongitudinally, the part 3 will be moved longitudinally with said bar.And, since each part 3 is connected with a corresponding part 7, itfollows that the part 7 must be moved with said part 3. The presentinvention includes means for selecting which levers 9 will be operatedefiectively to move the corresponding parts 1 and thereby the parts 3into engagement with the bar 8 for operation thereby. The operating bar8 is supported for .longitudinal movements between guide rollers 18.

A selecting bar 19 is supported by guide rollers 20 for longitudinalmovements paralinto and out of a slot 27 in the adjacent end of the arm21. Thus,.when.the pin 26 is engaged in the slot 27, said lever willmove the arm 21 and thereby the selecting bar 19 longitudinally from andto a starting position and to intermediate adjusted positions. To oneside of the bar 19 a selecting ratchet stop 28 (Fig. 2) is attached andis formed on its upper side with a series of ratchet teeth 29. There isat least one of said ratchet teeth for each part 1 included in theseries or parts for selective operation. That is to say, as statedabove, the embodimentof the invention which we have chosen forillustration is designed and adapted to select and operate any one orany number or all of the five parts 1 included in the series.Accordingly, we have shown six teeth 29; one tooth for each part 1 andone tooth for the entire series of said parts 1. Of course, the numberof parts 1 to be selectively operated may be varied without departurefrom the principle of the invention. This may include a variation in thenumber of the teeth 29. In mentioning that the device is illustrated forselectively operating five parts l-we have not intended to impose anydistinction upon the scope of the invention.

A pawl 30 is pivoted upon'a stationary support 31 and has a pointed end32 which escapes over the upper ends of the teeth 29 during movement ofthe selecting bar 19 from its idle or starting position. Obviously, thispawl 30 will prevent the selecting bar 19 from being returned to itsstarting position unless said pawl 30 be disengaged from the teeth 29.The present invention includes means for-disengaging the pawl 30 fromthe I teeth 29 and holding said pawl out of engagement with said teeth29 to permit the selecting bar 19 to be returned to its starting or idleposition. A detent 33 is pivoted on a stationary support 34 and isactuated by a spring 35 against a projection 36 on one side of the pawl30. The member 28 has a raised part 37 which will move under the end 32of the pawl 30 as the bar 19 approaches the limit of its extent ofmovement from starting position. The raised portion 37 will raise thepawl 30 until the projection 36 is above a shoulder 38 on the catch 33,permitting said shoulder to move under said projection 36 and therebysupport the pawl 30 in a position in which the end 32 of said pawl isabove and cannot engage the teeth 29. This will permit the selecting bar19 to be returned to its starting or idle position.

And, as said bar 19 approaches its starting by said bar 19 contacts withthe lower end of the catch 33 and pushes said catch 33out of engagementwith the projection 36. This permits the pawl 30 to drop into contactwith the member 28 preparatory for a selecting operation of theselecting bar 19.

Adjacent to one end of each of the bars 19 a disc 40 is rotativelymounted in a stationary support 41. Each disc 40 in the embodiment shownhas six fulcrum pins 42 projecting laterally toward the adjacent end ofthe lever 9. The discs 40 rotate about axes thatare parallel with theplanes of the pivots10, and are frictionally held by their suports 41until positionly rotated as hereinafter described. Each lever 9 has aprojection 43 designed and adapted to engage upon the properlypositioned fulcrum pin 42 when the corresponding lever 9 has beenselected 3 for operation. But, when a lever 9 is not selected foroperation, the projection 43 can move between the fulcrum. pins 42. Thatis to say, when it is desired to operate any one of the levers 9, thecorresponding disc 40 is turned to position in which one of the fulcrumpins 42 is immediately below the projection 43 on the selected lever 9;so that. when the opposite end of the lever 9 is raised 7 (Fig. 13), theprojection 43 on said lever will fulcrum upon-an'adjacent pin 42' andwill thereby be caused to move the part 1 which. in turn, moves the part3 to position in which the arm 13 on said part 3 is engaged in the notch15 in the operating bar 8. 'The normal or idle positions of all of thediscs 40 are such that no projections 43 will fulcrum upon pins 42. Thatis to say, in the Y normal or idle position of the invention, theprojections 43 on all of the levers 9 are free to move between thefulcrum pins 42 on the corresponding discs 40. H For each disc 40 theselecting bar 19 supports an actuating detent 44. The detents 44 aremountedon pivots 45, extent of pivotal movements of said detents beinglimited by pin-in-slot devices 46. The outer end of each detent 44 isprovided with a shoulder 47 and spaced therefrom the lower edge of eachdetent 44 is provided with another shoulder 48. The shoulders 48 arespaced from the ends 47 ofthe respective detents 44 according to thespacing of the teeth 29. Hence, when the selecting bar 19 is moved fromstarting position a distance equivalent to one ratchet tooth 29, theshoulder 48 on one of the detents 44 will be operated effectively toturn the corresponding disc 40 to place one of the pins 42 in positionto function as a fulcrum for the projection 43 of the correspondinglever 9. When the selecting bar 19 is operated a distance correspondingto two ratchetteeth 29, a different one of the detents 44 will positionits corresponding. disc 40 so that one 'ofthe pins 42 will function as afulcrumlfor the projection 43 of the corresponding lever 9, and so on. I

The movement of the selecting bar 19 from starting position to positionto locate a fulcrum pin 42 below the projection 43 of the selected lever9 consists in moving said selecting bar toward the left, as shown in thedrawings, to a position in which the pointed end 32 of the pawl 30 isabout half Way between two adjacent teeth 29. That is to say, theselecting bar 19 is moved to the left until the point 32 is about halfway to the next tooth .29 beyond the tooth corresponding to the shoulder48 of the proper detent 44. Then the selecting bar 19 is movedlongitudinally in the opposite direction until the tooth 29 which hadlast passed the point 32 engages or abuts against said point, as shownin Fig. 2. This causes the corresponding detent 44 to move a distancesuflicient for its shoulder 48 to engage one of the abutment pins 42 andthereby turn the disc 40 in a clockwise direction (Fig. 5) to positionin which said abutment pinis immediately below the projection 43 of theadjacent lever 9. By this operation all other discs 40 than the oneoperated as above described are turned to the positions shown at theright of Fig. 13 in which the projection 43 may pass between the fulcrumpins 42. Then, if it be desired to adjust another oneof the discs 40 ineffective position so that one of its pins 42 will function as a fulcrumfor the corresponding lever 9, the selecting. bar 19 is again moved tothe left the-required distance for the point 32 of the pawl 30 to restupon the inclined edge of the next tooth 29 beyond that tooth 29 thatcorresponds with the detent 44 that is to be used to turn the discs 40.Then the selecting bar 19 is again moved in the opposite direction, thatis, to the right, as seen in Fig. 2, which will cause the proper detent44- to turn the corresponding disc 40 to position in which one of thefulcrum pins 42 is immediately below the fulcrum projection 43 of thecorresponding lever 9. This leaves out of effective position the pins 42of all other discs than the ones that were operated as above described.

Or, if it be-desirable to operate all discs 40 of the series so as tocause an abutment pin 42 on every one of said discs to function as afulcrum for a corresponding lever 9,.the selecting bar 19 is moved tothe left (Fig. 2) until the last tooth 29 ofvthe series ofsaid teeth isbeyond and to the left of the pointed end 32 of the pawl 30. This placesthe ends 47 of all of the detents 44 in abgut the positions shownin'Fig. 9 so that a slight movement of the selecting bar 19 toward theright will turn all of the discs 40 a distance sufiicient to place anabutment pin 42 on each disc under the projection 43 of thecorresponding lever 9. v Movement of the selecting bar toin thisoperation as in others, is stopped by engagement of the proper tooth 29against the end of the pawl 30.

Next, the lever 24 is operated to move the selecting bar 19 toward theleft a distance sufiicient to cause rollers 49 on the selecting bar 19to enter cam slots 50 in the free ends of all of the levers 9 (Fig. 13)and thus raise the free ends of said levers 9. The levers 9 which havetheir projections 43fulcrumed upon pins 42 will thereby be operatedeffectively to move upwardly the parts 1. But, the

7 remaining levers 9, that is to say, the levers 9 whose projections 43do not fulcrum upon fulcrum pins 42, will simply be rocked upon theirpivots 10, as shown at the right of Fig.

l 13, and will not move the parts 1 from their initial or startingpositions. The selecting bar 19 is left in this position so as tosupport the levers 9 that had been operated.

As previously stated, the raising of a lever 9 raises the 'pivotallyconnected part 1 and the bracket 11,.thereby raising the part 3 untilthe arm 13 is' engaged in the notch 15 in the operating bar 8.Thereupon, the oper: ating bar 8 is moved toward the left from itsstarting position, thus moving the part 3 that is engaged therewith, asaforesaid, and along with it moving the part 7. In the embodiment shown,the'part 7 is a truck mounted on rollers 51 that operate along a track52. longitudinal movement ofthe erating bar 8 moves the part 3 from theposition shown at the right of Fig. 12 to the position shown at the leftof Fig. 12; that is to say, the part 3 is moved longitudinally adistance approximately equal to its length, which is sufficient to carrythe roller 4 on the left end of said part 3 beyond the bracket 11 and toengage in the bracket 11 the roller 4 on the right end of said part 3.Thus, as many of the parts 3 as had been selected will be moved.

A system of tong levers 53 has its upper end pivoted to a stationarysupport 54 and its lower end pivoted to the operating bar 8 and itsintermediate portion connected by a pivot 55 with one end of anactuating slide 56 operatively mounted between guide rollers 57. lheslide 56 has a slot 58 near its outer end corresponding to the slot .27that is in the end of the arm 21. In the embodiment shown, the lever 24ma be shifted to disengage the pin26 from t e arm 21 and to engage saidpin with the slide 56 in order to operate said slide and thereby theoperating bar 8, as described. The system of tong levers 53 will movethe operating bar 8 twicethe distance which the slide 56 is moved.

In order to restore the parts to their starting positions, the operatingbar 8 is returned to its starting position byoperation of the lever 24.Then the lever 24 is disengaged from the slide 56 and is oscillated toengage the pin 26 with the arm 21. Then the lever 24 is operated to movethe arm 21 and thereby This the selectin bar 19 to their 'idle orstarting positions, a approximately as shown in Fig. 6 in which nofulcrum pins 42 are below projections 43.

In the idle or starting position of the device the operating bar 8 is ina position in which all of the notches are above the projections 13-14so that, [when the respective parts 3 are raised, said projections 13-14will engage in the respect ve notches 15. "Then, when the-operating"'b'ar"8 is moved longitudinally, it will move'with it theparts 3 which are engaged therewith and will also move the parts 7 whichhave their parts 3 engaged with the bar 8. Further, in the normal oridle position, the selectm bar 19 is in a location in which the pointeend 32 of the pawl'3O seats upon the rachet stop element 28 between theselecting bar 19 and the abutment 39 and inwardly, that is, to the left,as seen in Figs. 2 and 8, beyond the last tooth 29. In this location ofthe selecting bar 19 all of the detents 44 are supported in a raisedposition, as shown in Fig. 3, because the lower edges of the shoulderedportions 48 of said detents are seated upon and supported by the pins42. We have already explained that the shoulders 48 on therespective'detents 44 are ,diiferent distances from the ends 47 of saiddetents to coordimate the devices in the positions. of said shoulders 48with the distances between the teeth 29. Thus, in Fig. 3 in solid lines,one of the shoulders 48 is shown and the shoulder on the next detentwould be approximately at the solid line a, and the others atapproximately the positions 6, c, d and 4, re-

spectively. Hence, a movement of the se-' lecting bar 19 to the left adistance equal to about the length of a tooth and a half 29 will movethe detent 44 shown in solid lines (Fig. 3) to about the position shownin Fig. 4, While the remaining detents will be upheld because theirshouldered portions 48 remain seated upon pins 42. Then a movement ofthe selecting bar 19 a distance equal to the length of about one-half ofa tooth 29 will turn the disc from the position shown in Fig. 4 to theposition shown in Fi 5 in which the uppermost pin 42 is directly belowthe projection 43 of the adjacent lever 9 so as to function as a fulcrumfor said lever 9. Then, after theselecting bar 19 has been I moved tothe right a distance equal to about per position and thereby engagingthe pro- I ate the bar 19 toward the left, as shown in the I A drawings,to its starting position, thereby permitting the part 1, the lever 9 andthe par-t 3 to return to their initial or starting positions. Then, inorder to restore the parts 3 and 7 to their starting positions, it isonly necessary to move the selecting bar 19 the full distance to theleft which again raises the lever 9 and thereby re-engages the part13.14 of the part I 3 that had been moved in the notch 15 of theoperating bar 8. Then the lever 24 is manipulated to move the operatingbar to its starting position, and is further manipulated to restore theselecting bar 19 to its starting position, thus permitting the parts 1,their levers 9 and the parts 3 to be restored to their startingpositions in which all. of the parts 3 are disengagedfrom the operatingbar 8.
